I have inquired 2 separate times and the rec was to replace.


It makes sense that professionals would suggest replacement...

For starters, controllers are relatively inexpensive compared to per/hr charges of trying to fix the existing equipment (i.e. likely not a huge savings between repair cost and replacement cost).

But then there's the issue of the unknown.
If a professional attempts to repair and fails, he's stuck in the catch-22 of needing to charge for his time to cover expenses, but having not accomplished anything for the customer. Plus, since it is an old unit, if something else goes wrong unrelated to the initial repairs, a homeowner might ask that the new repairs be done "under warranty" of any previous work the pro did.

So while it might make sense for a mechanic working on a $$$$$ piece of equipment to try various repairs to get you going, for an irrigation professional, working on a $$ to $$$ isn't work the risk.

On the other hand, if you try to repair it yourself, it will only cost you your time and the cost of the parts, and if you fail, that's all you're out, your time and cost of parts. If the cost of parts is much lower than the cost to replace, then it makes sense for you to try to fix it as a DIY project.

If the controller never moves on its own, no matter what you do, then possibly you might need both motors. Frankly, I doubt it.

Thanks.

How can I make sure that I only need the one motor and not both of the motors?

Indoor versions of the RC (RCBi) used a fuse instead of a circuit breaker. The rest is the same. Since there is no line voltage involved, and probably no soldering, it isn't a terribly difficult repair job.

Thanks, I will look into it. Is it something quite difficult? I have inquired 2 separate times and the rec was to replace. I actually like the mechanical timer, pretty simple. We do not get much lightening thank goodness. I also noticed that there is a fuse in the diagram of the controller but I do not see one on my unit. Is it behind the transformer?

You need a new clock motor - Rainbird part number 622874 ~ that motor does two jobs, first it keeps the time of day, and second, it moves the large wheel through the timed watering. A second motor is what moves the large wheel from one zone to the next. A top-flight sprinkler repairman can change out your old timing motor without too much effort.

For people who live in areas with frequent lightning, these old motorized controllers are worth the effort to maintain.

timer

Sorry I did not know where to start as far as the problems to the controller. The hour timer itself has stopped advancing. I can manually move the time and it will advance the day also. Once the control is activated it will advance through the zone cycle. The last time though it did not complete the cycle and stayed on each zone until I manually moved them. I can hear the clicking like a clock but no movement with time. Does this help in trying a diagnosis?

Thanks.

Replace nothing unless you personally know it needs replacing. The economics of controller repair (and the general lack of repair knowledge) make replacement easier than repairing. It does happen that Rainbird parts for this controller are still available. The controller itself has gone out of production.

You have still not stated just what the RC controller is doing, or not doing, that warrants replacement.

When my maintenance lawn person came by he said it was better to replace it for it was fairly old and several things needed to be changed ?( . Is it more reasonable to repair it?

You do know that RC controllers are still repairable. And you also know that the vast majority of solid state controllers employ a grounded power connection, which was not part of the RC construction.
